docker problem
hello everyone... I have deployed a serverpod project (dart) through a docker. but although the container is built correctly, I can't access it from the domain provided by railway.
The container should expose port 8080 but I can't get it to work and I'm out of ideas... can someone help me??
I leave you a copy of the dockerfile

WORKDIR /app
COPY . .

RUN dart compile exe bin/main.dart -o bin/main

please have your app listen on host 0.0.0.0 and the environment variable PORT, this PORT variable is auto assigned to your service, and without your app listening on it, railway won't know how to forward traffic to your app, thus you get that error page
